Application filed July 29, 1915.

To all 'whom it may concern:

Be it known that I, SEVERIN HaLvonsnN, a citizen of the United States of America, and resident of Seattle, in the county of King and State of l/Vashington, have invented certain new and useful Improvements in Paper-Feeding Mechanisms, of which the following is a specication.

My invention relates to feeding devices for signatures, papers and like articles, and consists of an improved feeding apparatus lby which the feeding of the papers, signatures or the like, one at a time, is insured. The object of my invention is to simplify the mechanisms formerly employed for this purpose as well as to improve upon the character of their operation, whereby the mechanism will, with certainty, feed a single signature or paper at a time without probability of feeding more than one at a time.

The particular parts and combinations of parts of which my invention consists will be hereinafter described and particularly pointed out in the claims. In the accompanying drawings I have shown my invention embodied in the form which is now preferred by me.

Figure 1 is a sectional elevation through the paper holding and feeding means.

Fig. 2 is a plan view of the same parts.

Figs. 3 and 4 are cross sectional elevations showing they parts in dierent positions.

Fig. 5 shows, in perspective, they cam track by which one set of the paper feeding needles are thrown out of action.

Fig. 6 is a plan view with partsbroken away showing one of the feed bars and its associated mechanisms. p

Fig. 7 is a sectional elevation showing like part-s to those in Fig. 6, and

Fig. 8 shows, in end elevation, the same parts as in Figs. 6 and 7.

One of the principal uses for my invention is for the feeding of papers in connection with stuffing apparatus and I will herein describe the same as applied to this use. I clearly realize, however, the adaptability of my invention for other uses, such as the feeding of signatures, pamphlets and other like articles, and do not wish to be Specification of Letters Patent.

understood as abandoning any rights for the device when used for analogous purposes.

The papers 6 are herein shown as placed within a container which has an inclined bottom, the side faces of the papers being in contact with this bottom. T he wall 5, which lies toward the lower end of this inclination, is provided with an inwardly turned ledge 50, upon. which the edges of the papers are supported. The papers should be placed in this compartment orcontainer, in such position that the folded edges of the papers are toward the side 5. The ledge 50 is positioned above the bottom of this compartment a distance which is determined by the thickness of the papers being operated upon. This distance should be suflicient to permit ready discharge of one paper beneath this ledge and not suiiicient to permit simultaneous discharge of two papers. This distance is preferably made adjustable, either by vertical movement of the ledge, or by vertical movement of the iioor of the compartment at this side. The iioor of this compartment is divided into two sections. The upper section 1, is, or may be, fixed in position.l The other section, which is formed by the member l1, is, or may be, vertically adjustable in position to control the gap between this part and the ledge 50, through which the papers are discharged. The section 11 is provided with a series of guidesfor grooves extending away from the discharge slot, in which the paper feeding members are mounted. These paper feeding members are shown in side elevation in Figs. 3 and at and in further detail in Figs. 6 and 7.

Each of the feeding mechanisms Comprises a bar 2, which is mounted to reciprocate within a groove formed in the member il. This reciprocation is shown as being secured by providing each bar with a downwardly extending arm 20, to which a link il is connected, this link extending to a crank arm 22, carried by a rock shaft 23, which rock shaft is oscillated between the positions indicated by full and by dotted lines in Fig. l, through the action of a rod 26, which is in turn reciprocated in any convenient and suitable manner. The crank Vwhich is mounted the feed bar arm 25 is provided with a slot 2T, for the reception of an adjustable connecting pin 28, whereby the extent of oscillation given to the shaft 23 and the extent of movement given members :2, may be adjusted.

The bars Q carry tivo sets of feeding members. The construction of these members in the tivo sets is essentially the same, but they are so positioned that one set is adapted to feed the paper in one direction, While the other set is adapted to feed it in the opposite direction. The feeding elements of each set consist of a block 3, which is pivoted at Se to the bar 2, and which carries proj ecting needles or pins 83, theser being inclined in the direction toward which they are eX- pected to move the paper. The blocks 3 are held in position to project the needles 33 slightly above the surface of the table, by means of springs 35. lVhile the above is the construction herein shown and the one preferred by me, other suitable feeding membersV might be employed Without departing from the essence of my invention.

The bar 2 is mounted toward the edge of the paper which is first discharged and reciprocates so as to be drawn entirely under the pile of papers and to be moved in the other direction so as to be Aproiected Well beyond the edge of the pile of papers, as is shown in F ig. l. l have shown tivo of the blocks 3 provided on each bar 2, positioned to move the paper in the direction which will discharge it through the gap beneath the ledge 50, and one of the feeding elements positioned inwardly from the tivoj ust mentioned and adapted to engage. and move the paper in the opposite direction. The latter set is provided, veach with a cam roller 3l, which adapted for engagement with a cam track so to positively lovver the needle carrying end of the block 3 beneath the snrface of the table, to thereby prevent its engaging with the paper.

The cam track is secured integral Vwith an angle shaped member 36, which is prrr vided with slots 3T, through which the securing bolts or screvfs are passed. By this means the position of the cam track may be adjusted to securethe depression of the feeding members of this set at the time desired.

have shown feed rollers el having feed tapes l() passing' about them and placed so as to receive the paper as its edge is projected through the opening under the ledge 50. rifhese tapes may be arranged to conduct the paper to any point desired.

The permanent, or fixed plate 1, Which forms part of the table or support for the papers, is provided with an opening yin Which is placed the plate or frame member ll, inV

9.. The opening provided for this purpose is not entirely closed by these parts` These parts are so designed that a space 10 provided, extend ing across the table, into vvhich the lowermost paper may be buckled or folded, as is shoivn at 6G in This is necessitated for reasons which will now be explained.

The operation of the device is as follo-vvs: Tvvlien the feed bars 2 are moved backward, or up the incline, this direction being such as to more therbar farther ander the pile of papers, the feed members, consisting of the set of blocks 3 and their attached needles which are toward the discharge side of the compartment containing the papers, will have no effect upon the papers to move them, for tlie'reason that the inclination of the needles is in the direction opposite to that of movement. rhe other set of blocks, 30

and their needles, Will not engage the papers to move them during the first part of this movement, for the reason that the cam trach 32 holds the roller 3l up, thereby depressing the needle end of these blocks, so that the needles are belov: the surface of the papers. llvlhen, however, the cam roller 3l is permitted to drop, by rolling ofi' of the cam track, the spring will throw the needles up Yinto engagement with the paper. rlhe feed bars 2 have not yet reached the limit of their motion and, in consequence, the lowermost paper Will be pushed backward under the pile, as has been shown in liig. l. In order to permit this, it is best to provide the gap l0, into `Which the fold 60 of the paper may be formed.

lVhen the feed bars 2 are moved in the opposite direction, the needles ofV the blocks 3 immediately engage the paper and advance it in the discharge direction. Vllhe preliminary backward movement of the paper has` been sufficient to `Withdraw it from the ledge 50, so that. when the discharge movement commences the paper Will be forced out be"- neath the ledge 50 and the movement vvill be carried to such an extent that the paper vv'ill be engaged by the feed roller il. lf the space 50 is properly adjusted, there ivill be no diilicnlty in passing a single paper, but tivo papers Will be too thicl to pass, the upper paper being therefore retained. ly this leans the feeding of more than one paper at a time is prevented. The feeding mechanism is also of such positive character that the feeding of one paper is insured, so long as any remain in the container.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is

l. A mechanism for feeding single papers from a pile comprising an under-support engaging the side faces of the papers, a restraining member engaging the edges of the papers and a narrow under-sopportfor the edges of the papers spaced above the main under-support to permit the Withdrawal of only one paper between them, means for moving the lowermost paper backward to clear it from said narrow support, and means for them moving it oppositely to withdraw it from beneath said narrow support.
